OK, so I've seen XBMC running on the IV but when I install it it just shrugs its shoulders and says ..."Unfortunately, XBMX has stopped." OK... Now is there a special version for MK802s? (yes I know I will search the forum...)

Never mind - upgrade the FW...

I think that's the first step for all issues isn't it... Lets see if it fixes my bluetooth issue too (i.e. yup it works fine, but after a sleep or a restart you have to repair..., not good).

OK, and I was wondering why the graphics looked a little ... pixelly.. so looked in hdmi - I'm using highest res (i.e. 1920 x 1080p @ 60Hz - more which my monitor/22" TV is more than capable of)... Noticed Screen zoom was up quite high.... So I turned it down, now its like in a window, but the graphics/text are fairly sharp - is it really running at 1920x1080 (Windows looks nice on this monitor in this res) or is it running at 720p? (changing from 1080 to 720 makes no difference to the screen size...)...

I guess again the first answer is "update the FW".. but this seems a bit... disappointing - a good job I'm a tinkerer/geek (depending who you ask...).

[Wondering if he could justify getting the Atrix Lapdock, and if it'd work with the IV...]

oh wow, it won't even boot up It doesn't even know which resolution to display. HDTV keeps switching between 720 and 1080p, stick can't make up it's mind and only barely get a glimpse of the android home screen occasionally for a second. Hope I can get a full refund but don't know about geekbuying returns. Guess I'll find out.

I used the stock wall wart then tried others without success. Now that I went back to the stock power it's able to display 1080p but now flashing to black screen, losing signal every few seconds. Driving me crazy, maybe it's updating in the background, it says it's up to date at 4.1 JB. I think I got a lemon, it won't even work on my other tvs, only on my high end Vizio. I'll keep trying but not for long. Thanks for the help though.

update, of course as soon as I click submit the device stabilizes even on my other HDTV. Blutooth fairy is behaving badly, have to re-pair mouse often. Black screen still happening when loading USB files. I hope updates fix these asap. I may stick with it now but a lot of my apps are not compatible with this new stick.

update 2 this gizmo is growing on me. It's still erratic with video problems but improving. It it seems to be breaking in and running really smooth most of the time. If this trend continues I'll likely keep it and wait patiently for a decent firmware. I've read Android 4.2 has created wifi issues so no hurry to try that. I have to say I'm really enjoying the quad performance running demanding games like Plants vs Zombies. Hopefully more apps will be optimized and compatible for the quad core sooner then later.

just to update, I found the problem with the video. Others have reported defective HDMI cables so I ditched the extension for a switch and problem solved. I even submitted a positive review on Amazon product page, very happy user.

I haven't seen this mentioned but Rockchip released a new SDK.

seems like a big deal to me but I don't know how this applies my RKM802iv

Ordered the MK802iv from CloudSto after reading on the forums that Chipset on this device (Mk802iv) is now upgraded / changed. I just want to ensure that I receive this new version. Have sent a email and tried calling the customer service number to check this - but no luck hope some one here reads this and provide some clarity ??
